Abstract

"COMPRESSOR ROTATIVO". Em um compressor rotativo para executar o suprimento de óleo aos rolamentos (32, 34, 45) através de uma passagem de suprimento de óleo principal (51) formada em um eixo de transmissão (17) empregando o diferencial de pressão entre a pressão de nível elevado e a pressão de baixo nível no invólucro (10), as partes vedantes (65) que têm uma estrutura à prova de ar são formadas em ambos os lados na direção do eixo de cada uma das faces deslizantes constituídas entre o eixo de transmissão (17) e os rolamentos (32, 34, 45), colocando as passagens de suprimento de óleo da parte de rolamento (59, 60, 61) entre a parte vedante (65), para aumentar a confiabilidade dos rolamentos (32, 34, 45) por impedimento da passagem de gás de alta pressão no espaço entre o eixo de transmissão (17) e os rolamentos (32 , 34, 45)."ROTATING COMPRESSOR". In a rotary compressor to perform oil supply to bearings (32, 34, 45) through a main oil supply passage (51) formed on a drive shaft (17) employing the pressure differential between level pressure low pressure in the housing (10), the sealing parts (65) having an air tight structure are formed on both sides in the direction of the axis of each of the sliding faces formed between the drive shaft ( 17) and the bearings (32, 34, 45) by placing the oil supply passages of the bearing part (59, 60, 61) between the sealing part (65) to increase the reliability of the bearings (32, 34, 45) by preventing the passage of high pressure gas in the space between the drive shaft (17) and the bearings (32, 34, 45).
